I'm guessing this PR should be converted to draft for now?

[jyan1999]

Ah yeah that would be fine. I am mostly done, but I keep forgetting to change some small details like README files

[micahcarroll]

Ah, wait, ignore my previous comment – I mistook the last commit deltas for the whole PR deltas, so I thought this PR was just adding 5 files from Overcooked Demo (not the whole thing), and so I assumed it was just a WIP.

Will review shortly!
